INVESTIGADOR PRINCIPAL
Dr. Antonio Vallejo
Catedrático de Universidad en el Departamento de Química y Tecnología de Alimentos de la Universidad Politécnica de Madrid. Desde hace más de dos décadas realiza estudios sobre el efecto del uso de N, aportado a través de fertilizantes, en la producción agrícola y contaminación del medio ambiente. Ha sido IP de varios proyectos nacionales y europeos y firmado numerosos convenios con diferentes empresas del sector de fertilizantes. Participó como experto en el EU Nitrogen Expert Panel y en el equipo de coordinación de ANEP-Agricultura en el periodo 2008-2012. Es coordinador del consorcio AGRISOST.

Perfil técnico e investigador del grupo
En el periodo 1990-2000 la línea del grupo se centró en lixiviación de nitratos por prácticas agrícolas y en balance de N. Desde 2000 aborda la ‘Evaluación de las emisiones de gases invernadero (GEI) y amoniaco en suelos agrícolas’. Es uno de los escasos grupos españoles que ha aportado resultados de emisiones de GEI en España, evaluando estrategias de mitigación basadas en el manejo del N y del agua. El grupo también trabaja en el desarrollo de tecnología que permitan reducir las emisiones gaseosas de sistemas agrícolas, relativa a inhibidores de la nitrificación y de la ureasa. Estos estudios se realizan gracias a la colaboración con empresas del sector de fertilizantes nacionales (Fertiberia; K+S plus Iberia, S.L; Eurochem Agro Iberica, S.L) que financian parte de la investigación.
